Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 Shown, the present invention comprises thigh connection mechanism 10, range of motion adjustment mechanism 20, flexible control mechanism 40 and shank connection mechanism 50, when designing, the rotation axis of patient's knee joint of the range of motion adjustment mechanism 20 and flexible control mechanism 40 must be collinear.

[0021] The thigh connection mechanism 10 of the present invention includes a thigh support cavity 11, an anti-slip sleeve 12 is attached to the inner wall of the thigh support cavity 11, a vertical opening 13 is arranged on the thigh support cavity 11, and at least one locking buckle is arranged across the opening 13 14. The locking buckle 14 is used for adjusting the tightness and fixing the anti-slip sleeve 12. Two connecting rods 15 and 16 are arranged on both sides of the outer wall of the th...

Abstract

The invention relates to a knee joint flexibility auxiliary recovery device which comprises a thigh connecting mechanism, a shank connecting mechanism, an activity range adjusting mechanism and a flexibility control mechanism. The activity range adjusting mechanism comprises an inner shell and an outer shell, the inner shell is connected with the thigh connecting mechanism, and a spline is disposed in the center of the inner shell and connected with a wobble wheel which is provided with a pair of oscillating rods. The outer shell is connected with the shank connecting mechanism. The outer shell is a ring gear and is provided with a pair of flanges, the two oscillating rods are provided with a pair of limit buttons between the two flanges, the two limit buttons are respectively connected with a fan-shaped gear, and the upper portions are respectively connected with a pointer. The outer shell is provided with a sealed cover. The flexibility control mechanism comprises an outer shell and an inner shell, the inner shell is connected with the left side of the shank connecting mechanism, and the outer shell is connected with the left side of the thigh connecting mechanism. A rotating shaft is disposed in the center of the outer shell and fixedly connected with a button, a flat spring is clamped on the inner side of the rotating shaft, and both ends of the flat spring are fixed on the inner wall of the inner shell. The knee joint flexibility auxiliary recovery device can be widely used in research of knee joint recovery and contribute to medical rehabilitation programs.

Description

technical field [0001] The invention relates to an auxiliary rehabilitation device, in particular to a knee joint flexible auxiliary rehabilitation device. Background technique [0002] Auxiliary rehabilitation devices for the knee joint can generally be divided into wearable and non-wearable. Wearable auxiliary rehabilitation devices refer to devices worn outside the legs of the human body, which limit the extension and flexion of the joints within a suitable angle range, or maintain the knee joints at a certain angle, so as to promote early recovery of knee joint function. At present, wearable auxiliary rehabilitation devices have a relatively simple structure, generally support and stabilize the patient's damaged knee joint, and are relatively simple to use. Non-wearable auxiliary rehabilitation devices are more powerful than wearable ones. They can increase the patient's muscle strength and knee joint flexibility and improve the patient's ability to control muscles. How...
